Trade Shows Regularly Attended

I attend a great many trade shows for my employers and make regular reports on product trends, technologies and other things I see there. My employers have always been extremely pleased at the depth and quality of these reports. On many occasions I was the only one from the company to attend one of these events and report back.  There are other ones, but these are the ones I most commonly attend.
